SPECIFICATION forming part of Letters Patent No. 278,201, dated May 22,1 883. Application filed March 18, 1882. (No model.)

To all whom tt may concern:

Be it known that I, JAMES E. TEGARDINE, of Chicago, in the county ofCook and State ot' Illinois, have invented certain new and usefulImprovements in Fountain-Pens, of which the following, in connectionwith the 'accompanying drawings, is a speciiicat-ion.

In the drawings, Figure 1 is a side view of a fountain-pen embodying myinvention. Fig. 2 is a vertical central section thereof. Fig. 3 is adetail of the pen-clamp, and Fig. 4 is a detail of the tip or feeder.

Like letters of reference indicate like parts.

A represents the handle, and B the pen.

Gis that part of' the handle which constitutes the ink-reservoir.

D is a diaphragm near the upper end of the This diaphragm has a centralconical opening, a, the smaller end of which is downward, as shown.

E is a hollow vertical screwextension on the upper end of the reservoir.In this extension are air-ports a a.

F is a cap screwed upon the said extension. By screwing' this cap up anddown the ports a a will be alternately opened and closed.

G is a slender rod or wire depending from the top of the cap F. This rodhas a taper point, b, and a conical shoulder, b', the latter ot' whichis adapted to close thc opening a.-

H is a hollow extension screwed into the lower end of the reservoir O,and this eXtension has an interior shoulder, c.

I is a tubular piece depending from the upper end ot' the extension H.

J is a split and curved tip or feeder screwed into the lower end ofthetube I. The split portion ot this feederis inclosed in a rubber sleeve,d.

Kis a point or supplemental tip projecting from and applied to the lowerend of the tip J. The pointK rests uponor near the nib oi' the pen, asshown. The upper part of the tip J contains a conical opening, c, intowhich the lower end of the rod Gtits removably, and immediately belowthe opening e is a larger channel, e". v

L is a spring-metal clamp, split longitudinally and arranged in theextension H. The pen is slipped in between the extension H and the partL, the spring action of the latter, which is outward, holding the penremovably in place for use.

M is a cover, which, when the pen is iu use, may be slipped removablydown over the cap F. When the pen is not in use the cover M is slippedremovably on the lower end of the part H, and protects and shields thepen.

In order to prepare the peu for use, I lill or partly till the reservoirG with ink or writinguid, removing the extension H for that pur .pose,and then, after the reservoir has been iilled and the extension Hreplaced, unscrewing the cap F far enough toopen the air-ports a' a',and by this means also leaving the opening a open, as the conical part bwill then stand above the said opening, and also leave open the conicalopening c in the tip J. The ink, therefore, depositsitself upon the nibof the pen, and will feed the pen as fast as the ink is shed by writing.in use I cover it with the cover M, in the manner described, and screwdown the cap F until the part b enters and closes the opening a, theopening c and ports a a thus preventing the ink from then leaking outofthe pen. By making the channel c larger than thcopening e anyink-crusts or foreign matter clogging the smaller opening may be pusheddown into the larger, where it will escape, the. point ot' the part Grbeing forced into the opening ein order to clear it. By splitting thetip J it may readily lbe cleaned, in ease it becomes clogged, the'sleeve d being removed to admit ot' cleaning, and replaced to preventthe ink from escaping, except at the lower end ot' the tip.

it is not absolutely essential that the opening a and the ports a ashould he closed at the same time, for it is obvious that the ink cannotleak out ot' the upper end ot' the pen holder or handle when either thesaid opening or the said ports are closed.

Having thus described my in vention,.what I claim as new, and desire tosecure by Letters Patent, isl The combination, with the in k-reservoirand pen, ot' the split feed-tip and its rubber sleeve d, substantiallyas and for the purposes specied.

JAMES E. TEGARDINE.
